Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

Runtime: Node.js
npx -y @blockrun/mcp
claude mcp add blockrun -s user -- npx -y @blockrun/mcp@latest
{ "mcpServers": { "blockrun": { "command": "npx", "args": ["-y", "@blockrun/mcp"] } } }You supply: ~$5 USDC on Base or Solana in an auto-created wallet (pay-per-call), optional SOLANA_WALLET_KEY
claude mcp add satohub-blockrun-mcp -- npx @blockrun/mcp
A local server: your client runs this command on your machine. Installing runs third-party software under your own credentials. Sato Hub publishes the documented invocation and, where the harness reproduced it, the date it did — neither is a safety review.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 30 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Every one of them passed, so the rate covers them too.
Last 30 days — to 2026-10-31, one point per UTC day
A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.

blockrun-mcp v0.55.0 — Arc as a third payment chain
Added — Arc as a third payment chain blockrun_wallet action:"chain" chain:"arc" pays on Circle's Arc (eip155:5042) through arc.blockrun.ai, from the same EVM key and address as Base, funded with USDC on Arc. Arc serves everything Base does. status shows the Base, Solana and Arc balances; the Arc balance is read from the Arc gateway, or from ARC_RPC_URL when set. Setup, the funding QR (EIP-681 on c
blockrun-mcp v0.54.7 — Mistral Large 4 reserves its list price
Fixed — Mistral Large 4 reserves its list price Mistral's launch promotion ended and the gateways moved mistral/mistral-large-4 from $0.68/$2.09 to $1.36/$4.18. The price row follows, so an explicit call reserves the real rate instead of half of it.
blockrun-mcp v0.54.6 — chore: VERSION 0.54.6 to match package.json
Added — Gemini 4 Argon price row google/gemini-4-argon (live 2026-10-20 on Base and Solana) reserves its own $2/$10 per 1M instead of the $5/$30 default. That is Google's rate through 2026-11-30; it moves to $4/$20 on 2026-12-01. Argon has no long-context tier. It is priced only: no routing tier or mode includes it.
blockrun-mcp v0.54.4 — a Solana video settle whose outcome is unknown is waited out, never "no charge"
Fixed — a Solana video settle whose outcome is unknown is waited out, never "no charge" ( #177 ) When a finished video's payment settle times out, sol.blockrun.ai answers 402 Payment settlement outcome unknown with Retry-After and holds the job; other polls get settlement in progress on a concurrent poll . The client ignored Retry-After , spent its three re-signs about 15s into a 90s hold, and rep
blockrun-mcp v0.54.3 — Solana polls prove the wallet; the decide skill teaches Decisions
Changed — Solana media polls prove the wallet instead of paying ( #176 ) On the Solana wallet rail, a pending video job used to need a fresh SPL payment signature on every poll (~20s apart): a payment is a transaction pinned to a ~60-90s blockhash, and it was the only proof of who was asking. sol.blockrun.ai now also accepts an ownership proof: an ed25519 signature by the submitting wallet over bl
blockrun-mcp v0.54.2 — fix(polymarket): a withdrawal that may have moved money is never signed twice
Fixed — a withdrawal that may have moved money is never signed twice A retry that resolved the earlier withdrawal went on to sign another. The pendingWithdraw guard cleared itself when the earlier transfer turned out settled (relayer STATE_MINED / STATE_CONFIRMED , or an EOA receipt) and the same confirm:true call then signed a fresh transfer on top of it. Resolving the earlier withdrawal now ENDS
